This Kooks Shorty Catted X-Pipe is specifically designed to fit the 2005-2010 4.6L GT and Bullitt Mustangs with either Kooks Manual or Automatic Long Tube Headers installed. It will not install properly without the headers because it is shorter than the factory x pipe.

The Kooks Catted X-pipe (05-10 GT w/ Long Tube Headers) will be a great X pipe for your car. We only carry the Kooks off-road and catted X-pipe. Both will be the same just one will not have any cats making it louder.

My mustang is my first car and every time I look at it, I remember how lucky I am. Ever since I saw a grabber blue GT500, I knew I had to have a grabber blue car. I've done a few modifications to the car since I've gotten it, and of course there's many more to come.
